From what you guys saying the leung yee ma stance bieng like bow & arrow but sideways, sounds like it's close to or similar to a lot of other southern lin wan kuen stepping.
We have a 7-strike lin wan sequence in Hung Ga's FHSYK for example that steps just like that, and I've seen it often in Lama-influenced arts, often with their "half-moon" stepping where they slide the stance forwards with the backleg at the same time.
As for tucking thumb on the outside of the hand rather than cupping it, that's pretty standard too, particularly when throwing sao choy's or charp choy. IMO Anyone who's hit a heavy bag or a block downwards on their thumb stuck under their fist should know better than to keep it there for those strikes.
It's a trivial matter and not a style-thing to switch the thumb around based on what your type or target is, it's really not some "signature" thing. But I also know of some other styles like a local Jow Ga school that makes it a point to always tuck the thumb on the side, even on straight jabs or crosses.
